Question

Enzyme catalase occurs in

• A. Lysosome
• B. Sphaerosome
• C. Peroxisome
• D. Peroxisome and glyoxysome

Answer 1

The correct option is D Peroxisome and glyoxysome

• The enzyme catalase occurs in Peroxisome and glyoxysome.
• The enzyme catalase is found all living organisms such as bacteria, plants, and animals.
  
• Its main function is to catalyze the breakdown of hydrogen peroxide into water and oxygen and thus, protects the cell from oxidative damage from reactive oxygen species.
• The peroxisome is a single membrane-bound organelle which contains oxidative enzymes and is responsible for lipid production and oxidation reactions within the cell.
  
• Similarly, glyoxysome is specialized peroxisome which is found in fat storage tissues of germinating seeds.
• So, the correct answer is 'Peroxisome and glyoxysome'.
